The present study was conducted to elucidate the clinic-pathological aspects of gastrointestinal tract (GIT) disorders in sheep. Study was conducted on 21 (6 healthy sheep and 15 diseased sheep) and 12 carcasses of sheep/lamb brought for postmortem to the Department of Veterinary Pathology, LUVAS, Hisar. This study revealed that incidence of GIT disorders was maximum in sheep of age group 2-6 months and overall incidence was more in females than male sheep/lambs. Major gross pathological changes noticed were congestion in abomasums, catarrhal and hemorrhagic enteritis, congestion in kidney, oedema and enlargement in lymph node, congestion and petechial haemorrhage in spleen and congested heart. �In liver, most prominent change was congestion followed by necrotic foci, fibrosis and abscess in liver and in case of lungs, congestion, emphysema and consolidation were seen. Histopathologically, changes in abomasum were oedema, congestion and mononuclear cells infiltration in mucosa and submucosa. In intestine, there was oedema, mild congestion in mucosa and submucosa, haemorrhages in mucosa, desquamation of mucosal epithelium, goblet cell hyperplasia and replacement of glands by mononuclear cells. Liver revealed congestion of blood vessels, degenerative changes in hepatocytes including cloudy swelling, fatty changes, congestion in sinusoids, dialatation of sinusoids leading to atrophy of hepatocytes, leucocytic infiltration in portal triad area and bile duct hyperplasia along with fibroblast proliferation. In heart congestion and oedema were seen in myocardium along with leucocytic infiltration, sarcocystosis in cardiac muscle and hyalinization in myocardium along with mononuclear cell infiltration. In lungs changes including oedema, congestion, emphysema, serous inflammation, thickening of interlobular septa, fibrinous pleuritis and peribronchiolar lymphoid follicle formation were observed and� In kidneys there were congestion, focal interstitial nephritis, hyaline degeneration, coagulative necrosis and infiltration of leucocytes predominantly mononuclear cells.

Key words: Pathological studies, Sheep and Gastrointestinal tract disorders.
